Hi About 3 years ago, when Covid started and it was difficult/impossible to see a GP, I started taking B12 supplements 3-4 times weekly.
I was experiencing many symptoms - fatigue and tingling and breathlessness amongst them.
Whilst not wanting to diagnose myself, I felt I had little choice given the GP situation, plus my daughter is B12 deficient, and had the same symptoms as myself.
Fast forward to November '21 and I was diagnosed with thyroiditis. By this time I was feeling so much worse, and had been to A&E a couple of times due to palpitations and blood pressure/sugar spikes.
I was tested for diabetes - which was fine.
I then joined this forum, who told me I had Hashimoto's - thank you!
Since my diagnosis I have had little help from my surgery. I have insisted on TSH blood tests, and following advice on this forum, have tested privately for the FT3/FT4 and vitamins.
I am not on Levothyroxine, as my GP says my TSH isn't high enough. I did ask another GP at my practice, and I was told the same.
Anyway now I have gradually been feeling worse, I have fatigue/tingling/breathless/weakness/pulsatile tinnitus and more.
I paid privately for an MRI scan last November, because of the tingling and pulsatile tinnitus. Fortunately that was fine, but left me none the wiser.
More recently my GP arranged blood tests for penicious anaemia. I told her I had been supplementing B12 for some while.
The results came back as 'satisfactory'
I was referred for a gastroscopy towards the end of last year, and it was established that I didn't have gastritis as suspected, but peptic ulcer disease.
I have noticed my folate tends to be quite high, I'm not sure if that is relevant?
At this point I don't know what to do, if this is a B12 deficiency causing my tingling symptoms, how will I know?
I wish I hadn't taken the supplements, but I felt so ill.
Before my most recent blood test, I did stop the B12 about 3 weeks before, and my B12 active level dropped by around 100.
I have included my recent blood tests(including GPs) - my TSH has dropped from 5.47 even though I actually feel worse.
I am gluten/dairy and soy free. I take a D3/K2 spray daily, use an iron spray 3 times a week, and eat iron rich foods.
Could do with some advice on what to do next?
